Explanations:The Andaman and Nicobar Islands are a group of islands located in the Bay of Bengal, forming a Union Territory of India. These islands are known for their unique geographical features and administrative significance. The question tests the knowledge of specific facts related to the islands, including their volcanic activity and administrative details.
Barren Island, one of the islands in the Andaman and Nicobar group, is an active volcano. It is the only active volcano in India and has been active since the early 20th century. The volcanic activity on Barren Island is a result of the tectonic movements in the Indian Ocean, which have created a subduction zone where the Indian Plate is moving under the Eurasian Plate. This tectonic activity has led to the formation of the Andaman and Nicobar Islands and the presence of an active volcano on Barren Island.
The Andaman Islands, which include Barren Island, are the only location in India where active volcanoes are found. This makes the Andaman and Nicobar Islands unique in terms of their geological features. The volcanic activity in this region is a significant aspect of the islands' geography and has been studied extensively by geologists and volcanologists.
